ROUTINE MAINTENANCE

• Check the power cable, high-pressure pipe, connectors, gun and lance
pipe. If one or more parts are damaged, do not use the high-pressure
water cleaner and contact a QUALIFIED TECHNICIAN.
• Cleaning of inlet water filter (18).
• Unscrew the hose connector (25) O (27) and remove the filter (18).
Cleaning the filter under running water or compressed air is generally
sufficient. In more difficult cases, use a scale-removing product or replace
it by contacting an authorised assistance centre to purchase it.
• Refit the filter and tighten the hose connector.
• Cleaning the nozzle.
It is usually sufficient to clean the hole of the nozzle with the pin supplied
(31). If this operation fails to satisfactorily clean the nozzle, replace the
latter by ordering a spare part from an authorised service centre.
The nozzle is replaced using the key (32) (supplied).

SUPPLEMENTARY MAINTENANCE

• Check the pump hydraulic circuit (water).
• Check pump fixing.
